Summary: This study found that melatonin promotes the growth of the halophyte Limonium bicolor under salt stress by improving photosynthesis and antioxidant enzyme activities. It also showed that melatonin upregulates the expression of genes related to photosynthesis, reactive oxygen species scavenging, and mitogen-activated protein kinase (MAPK) in L. bicolor under salt stress, thus improving salt tolerance.

Summary: With global increases in saline soil, understanding salt tolerance mechanisms and strategies to improve crop salt tolerance has become increasingly important. This study identified the uncharacterized gene Lb1G04202 in the halophyte Limonium bicolor, which was highly expressed in salt glands after NaCl treatment. Heterologous expression of Lb1G04202 in Arabidopsis thaliana resulted in improved growth and salt tolerance compared to the wild type, potentially through increased proline synthesis.

Summary: In this study, LbMYB48 gene was found to be induced by salt stress in Limonium bicolor, and it regulates the development of salt glands and salt tolerance by modulating the expression of genes related to salt gland development and salt stress response. Heterologous over-expression of LbMYB48 in Arabidopsis thaliana enhances salt tolerance through stabilizing ion and osmotic balance.

Summary: The study showed that LbTRY from Limonium bicolor promotes root hair differentiation in Arabidopsis, with its expression affected by NaCl treatment. Heterologous expression of LbTRY in Arabidopsis influenced epidermal differentiation and increased root hair development, along with upregulating genes involved in these processes. Additionally, LbTRY reduced salt tolerance in transgenic lines by increasing ion accumulation and decreasing osmolytes.

Summary: In this study, a new DBF1 gene from the moss Dicranum scoparium was identified and characterized. The DsDBF1 protein was found to encode a 238 amino acid polypeptide with a classic AP2 domain, and it showed significant upregulation in response to various abiotic stresses. This findings suggest that DsDBF1 could be a potential candidate gene for improving stress tolerance in crop plants, and the characterization of transcription factors in stress-tolerant mosses provides insights into plant adaptation mechanisms.

Summary: In this study, a new DREB gene, ZmDREB2.9, was identified and characterized in maize. It was found to have two splice isoforms and showed differential expression in various tissues. Comparison with other genes revealed that ZmDREB2.9-S, ZmDREB2.2, and ZmDREB2.1/2A may play important roles in maize stress resistance.

Summary: In this study, a transmembrane protein called LbRSG was found to play a positive role in salt gland development and salt secretion in the recretohalophyte Limonium bicolor. The highly negatively charged regions in the extramembrane loop were identified to be important for salt tolerance. Additionally, the interaction of LbRSG with PGK1 and BGLU18 was proposed to enhance salt tolerance in salt glands.

Summary: The integrative transcriptome and proteome analyses of Limonium bicolor revealed numerous candidate members involved in salt secretion from salt glands. This study identified differentially expressed transcripts and proteins related to salt-tolerance mechanisms, particularly those involved in transmembrane ion transport. The correlation between transcript and protein profiles indicated key players in salt tolerance, such as cellulose synthases and annexins, providing insights into the molecular mechanisms of salt tolerance in recretohalophytes.

Summary: In this study, the DREB A1 and A2 genes involved in plant stress responses were identified and characterized in garlic. The expression patterns of these genes were analyzed in garlic cultivars with different sensitivity to cold and Fusarium infection. The results showed that these genes had different responses to fungal infection and cold exposure, and could be potential targets for breeding stress-tolerant varieties.

Summary: The addition of NO can reduce the relative conductivity of tea leaves, inhibit the elevated malondialdehyde content, promote the accumulation of proline, soluble protein and sugar, increase the superoxide dismutase, catalase activities, thereby alleviating the damage of cold stress on tea leaves. The study provides significant insights into how tea plants sense and defend against chilling stress, contributing to improving production levels and economic benefits, as well as offering theoretical foundations for controlling chilling stress in tea plants.

Summary: The study identified 20 L. bicolor MAPK genes that respond to salt, drought, and ABA stress, with LbMAPK2 playing a key role in salt gland development and salt secretion. The findings provide insights into the molecular mechanisms behind salt gland development and salt secretion in L. bicolor and lay the groundwork for exploring the biological functions of MAPKs in extreme halophytes.

Summary: Halophytes are essential for studying salt-tolerant genes in high-salinity environments. This study demonstrates that the LbCPC gene negatively regulates salt gland development in Limonium bicolor. In addition, the study reveals that LbCPC overexpression in transgenic Arabidopsis lines leads to reduced trichomes and increased salt sensitivity.
